  Further, as described above, even if the protruding direction of the substrate fixing protrusion 85 protruding from the press switch forming portion 81 is directed in a direction different from the moving direction (opening / closing direction) of the mold used for forming the base 50, Since the opening portion 93 (93B) is provided at the base portion protruding from the substrate direction changing portion 87, it is possible to prevent the mold structure used when molding the base 50 from being complicated, and the two molds K10, The base 50 can be easily molded only with K20.

  Furthermore, in this rotary electronic component 1-1 with a press switch, the second circuit board 25 of the flexible circuit board 20 is bent from the upper surface of the press switch forming portion 81 along the lower surface thereof through the tip side. The bending angle of the second circuit board 25 does not increase (about 90 ° at the maximum), and from this point, the circuit pattern in the second circuit board 25 is hardly damaged, and problems such as poor connection do not occur.

  FIG. 12 is a longitudinal sectional view (a sectional view of the same part as FIG. 3) of a rotary electronic component 1-2 with a push switch according to a second embodiment of the present invention. In the rotary electronic component with pressure switch 1-2 shown in the same figure, the same or corresponding parts as those in the rotary electronic component with pressure switch shown in FIGS. Is suffixed with "-2"). Note that matters other than those described below are the same as those in the embodiment shown in FIGS.

  In the rotary electronic component 1-2 with the press switch, the only difference from the rotary electronic component 1-1 with the press switch is the mounting state of the second circuit board 25-2 on the press switch forming portion 81-2. It is. That is, in the rotary electronic component 1-1 with the press switch, the second circuit board is bent by being bent from the upper surface of the press switch forming portion 81 along the circuit board mounting surface 83 on the lower surface through the tip side. 25 is attached to the press switch forming portion 81. In the rotary electronic component 1-2 with the press switch, the second circuit board 25-2 is double-folded on the lower surface of the press switch forming portion 81-2. Is attached to the circuit board attachment surface 83-2. Even if comprised in this way, the effect similar to the said rotary electronic component 1-1 with a press switch is exhibited.

  Further, according to the rotary electronic component 1-2 with the press switch, the second circuit board 25-2 is not positioned on the upper surface of the press switch forming portion 81, and therefore the rotating body 120-2 is mounted on the second circuit board 25-2. It is possible to reliably prevent contact.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings. Is possible. Note that any shape, structure, or material not directly described in the specification and drawings is within the scope of the technical idea of the present invention as long as the effects and advantages of the present invention are exhibited. For example, the detection means is not necessarily limited to a combination of a slider and a sliding contact pattern, and may be any configuration as long as the output signal is changed by the rotation of the rotating body. In the above example, one long opening is provided for molding two board fixing protrusions protruding from the circuit board mounting surface on the lower surface of the press switch forming part. Small openings corresponding to the protrusions may be provided separately.

  Moreover, as long as there is no contradiction in the objective, a structure, etc., the embodiment shown by the said description and each figure can combine the description content of each other. In addition, the above description and the description of each drawing can be an independent embodiment even if it is a part of it, and the embodiment of the present invention is an embodiment in which the above description and each drawing are combined. It is not limited to.
